begin with a v, end with oltage. voltage. voltage, very good. okay, we're on to this stuff. not so bad, yeah. but notice i have a wooden handle. why the wooden handle? it's a good insulator. electrons won't flow very readily through a wooden handle. if i put this down on top of there, should this be charged? i turn it over and it isn't. but what happens when i touch it with my finger? see that, see that, see the difference? isn't that neat? okay. so we find it's charged when i touched it with my finger. let's take a look at this in more detail. here's my piece of plastic material and i beat a negative charge on there, yeah. and i took the pie pan and i put the pie pan on there like that, okay? now, what happens in that pie pan? any free charges in that pie pan? yeah. any charges in that pie pan? show me the piece of material with no charges. no way. there's charges in everything. there's atoms in the pie pan. and aren't the electrons loose in all metals? isn't that true? so the electrons are gonna be repelled by the electrical-- by the negative plastic. so the electrons are
